The security architecture of Oracle Fusion Applications is fundamentally based on Role-Based Access Control (RBAC). The most effective and architecturally correct method to minimize data exposure is to ensure the agent operates under a security role with the least privilege necessary for its function. This involves configuring the agent's access rules to align with a user role that has been granted access only to the specific business objects and data attributes (fields) required for summarizing shift data. Oracle Fusion's data security policies, which are part of the RBAC framework, can restrict access down to the attribute (column/field) level, thereby preventing the agent from accessing unrelated or confidential information at the foundational security layer.

B. Set up the agent for public data sharing to promote transparency

This action directly contradicts the stated goal of minimizing exposure of confidential information and would introduce a severe security risk.

C. Limit the agent’s queries and responses to specific, relevant business object fields

While this is a good development practice, it is a secondary control. The primary and authoritative security mechanism in Oracle Fusion is the RBAC model. Proper security should be enforced by the platform's security policies (Option A), not rely solely on the agent's client-side code.

1. Oracle Fusion Cloud Applications - Securing Your Applications Guide: This guide details the security architecture

emphasizing Role-Based Access Control. It states

"Oracle Fusion Cloud Applications security is a function- and data-based security model that is organized by roles." This supports the principle of using roles (Option A) as the primary security mechanism.

2. Oracle Fusion Cloud Applications - Implementing Security Guide: This document explains the implementation of data security

including at the attribute level. It describes how data security policies

which are assigned to roles

can secure attributes. "You can secure a logical entity's attributes by creating a policy for an attribute group." This confirms that field-level security is an integral part of the RBAC setup described in Option A.

3. Oracle Fusion Cloud HCM - REST API for Common Features: The documentation for using REST APIs notes that access is controlled by privileges granted to roles. "Before you can use a REST API

you must grant a function security privilege for the required REST resource to a custom role." This reinforces that role configuration is the prerequisite and primary control for any data access.
